Contribution

It introduces a straightforward model of direct gauge mediation that solves key problems without fine tuning, expanding the possibilities for supersymmetry phenomenology.

Findings

All key supersymmetry issues are addressed simultaneously.

Model parameters are testable at the LHC.

No fine tuning required in the proposed model.

Abstract

In the context of direct gauge mediation Wess-Zumino models are very attractive in supersymmetry model building. Besides the spontaneous supersymmetry and R-symmetry breaking, the problems of small gaugino mass as well as {\mu} and B{\mu} terms should be solved so as to achieve a viable model. In this letter, we propose a simple model as an existence proof, in which all these subjects are realized simultaneously, with no need of fine tuning. This completion also implies that much of parameter space for direct gauge medition can be directly explored at LHC.
